Application filed November 1, 1912. Serial No. 729.007.

lie it known that l. Farc LnoroLn HUGO (Hisuy. a subject of the King of (ireat Britain` and residing at Deal. in the county ot' Kent. England. have invented certain new and useful improvements in or Relating to rushes. ol' which the following is a specification.

The invention relates to the type of brush wherein the brush head is adapted to be separated from its frame so that it may be changed for a fresh one or removed for cleansing so as to prevent injury to the frame of the brush.

The objects of the present invention are to obtain simple means for securing the brush head in its frame and in an improved and'rapid method of manufacture of the brush backs.

ln the accompanying drawings :-Figure l is a face view partly in section of a hair brush constructed according to the present invention. Fig. 2 is a longitudinal section taken on the line 1-1 of Fig. l. Fig. 3 is a horizontal section taken on the line 2 2- of Fig. 1. Fig. 4 is a face view of ay blank for a brush back. Fig. 5 is an end view thereof. Fig. G is an edge view illustrating the feet of the blank pressed into position. Fig. 7 is an end view thereof. Fig. 8 is a face view of a hair brush illustrating a modified construction of sliding catch and brush back. Fig. 9 is an end view of the brush h ad separately and Fig. lO is a part longitudinal section taken on the line 3 3 of Fig. 8.

ln the several figures of the drawings like parts are indicated by similar letters of reference and Fig. 10 is drawn to an increased scale with respect to the other figures of the drawings.

Referring to Figs. l to 7 a represents a brush back which is formed of metal or alloy by casting or otherwise. or it might be formed of other suitable material, b represents a rubber packing ring stretched around the end of the back a., c represents the handle frame for carrying the back l and fl represents the bristles. The hack a is according to one arrangement first formed as a blank as shown at Figs. 4 and 5. with projections a a* ai'. which are pressed down to form feet a a* ai and the feet a are separated by a space a3 so that they steady the back a when in the handle frame c assisted by the rubber packing ring b which is arranged in the notches a2 and between the back and the edge of the recess c of the holder c, (.)r the packing ring might be dispensed with. The feet a', a4, ai are pressed down at nearly right angles with the face of the blank. the feet a being inclined to correspond with the overhanging part el' of the recess c' and the opposite end of the back n is formed witha tapered perforation to co-act with the correspondingly formed end of a sliding catch u @he opposite end thereof being' acted upon by a spring e' and provided with a knob e2 by means of which the sliding catch may be retracted to release the brush back a. The feet a', at, (L5 permit of ventilation between the handle frame c and the back a so that when wetted the bristles (l will more readily dry atthe roots. Then the back a is in the blank and plane form the perforations (LX. for the bristles are punched at right angles to the face of the back a. after which the blank is domed so as to give the perforations a* the required angles. The foot a is split to enable it more readily to be pressed down at nearly a right angle which split then becomes closed so that a circular tapered perforation a is formed to accommodate the end of the catch e.

l'eferring to Figs. S to l0. In this case the catch e is formed to engage the bottom of a tapered hole o in the inner end of the back a to vfirmly secure the parts, and the outer end of the catch c is screw threaded at e* to co-act with a corresponding thread in a nut c3 fixed in the handle of the, handle frame o and by turning the head c2 the brush head may be released. The back (zin this case is formed by casting the feet a a*t a5 integral therewith.

By the means hereinbefore described, al brush may be replaced by a fresh one or removed for cleansing so as to prevent injury to the handlel frame of the brush.

The brush backs (I may be mounted in any desired frame such for example as used for military brushes.

llaving now particularly described and ascertained the nature of the. said invention and in what manner the. saine is to be performed. l declare that what claim is 1k ln a brush. in combination. a frame provided lwith a recess. a brush back carrying bristles. said back being provided with spaced .feet engaging the bottom of said recess, said back being of smaller area than will be provided Cornu' nixes his signature in presence of Suid recess whereby a space and the Walls two witnesses.
